6.2(9)S32

Description (partial)

Symptom:
M9250i and M9148s have hardware limitation in slowport oper delay. The slowport oper delay value may not capture the exact R_RDY delay experienced by the port if there is a continuously constant R_RDY delay is introduced(by test setup) and there are frames dropped due to Timeout.
However in real time scenario, there is less likely a continuous R_RDY delay present for long time. Real time scenario is basically expected to be random. In such case, the slowport oper delay computation works correctly most of the time..
Conditions:
Applies to MDS 9250i and 9148S only.
